CO.0 : Open circuit or short circuit to earth
CC.1 : Short circuit to + 12 V
NOTESConditions for applying the fault finding procedure to stored faults:
The fault appears after running command AC024 Sequential actuator control.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Disconnect the battery.
Disconnect the modular connector, and check the cleanliness and condition of the connections.
Disconnect the computer. Check the cleanliness and condition of the connections.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance to earth, to + 12 V of the following
connections:
(see System operation and Allocation of computer tracks on the modular connector)
●connection code 5AU, between components 119 and 754,
●connection code 5AV, between components 119 and 754,
●connection code 5AX, between components 119 and 754,
●connection code 5AW, between components 119 and 754,
●connection code 5AY, between components 119 and 754,
●connection code 5DL, between components 119 and 754,
●connection code 5DM, between components 119 and 754,
●connection code 5BA, between components 119 and 754,
●connection code 5AZ, between components 119 and 754,
●connection code 5BX, between components 119 and 754.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
With the ignition on, check for + 12 V on connections 5BA and 5AU of component 754.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
Reconnect the modular connector.
Measure the resistance of component 754 between the following connections:
●connection code 5BX,
●connection code 5BA.
If any of the connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Replace the solenoid valve or the electric/hydraulic interface wiring harness if the resistance is not 1 Ω ± 0.12
at 23˚C.
If the problem is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
